FRANCIS H. HAMBLETON, OF BALTIMORE, MARYLAND.

. GAS-CONTROLLING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 364,644, dated June 14, 1887. Application filed July 3, 1886. Serial No. 207,062. (No model.)

To all whom'it may concern.-

Be it known that I, FRANCIS H. HAMBLE- TON, of the city of Baltimore and State of Maryland, have invented certain Improve: ments in Gas-Controlling Apparatus, of which the following is a specification.

This invention relatesto means for operating the valves which control the flow of gas to and from a series of gasholders from one point, and to indicate whether the said yalves are open or closed.

In the further description of the said invention which follows reference is made to the accompanying drawings, forming a part here of, and in which- Figure I is a plan of the regulating-station and the holders together with the valves and the means of connecting them with the said station. Fig. II is a-vertical section of the station, showing the arrangements of the connections therein. Figs. III to-IX, inclusive, are details of the invention on anenlarged scale. Fig. X is a sectional view of the pipes and valve for communication between the holders.

A is the regulatingstation, from which the valves, hereinafter alluded to, are operated, and B B are the gas-holders, six of which are represented. The valves which control the flow of gas to and from the holders are denoted by G, H being the communicating-pipes. (See Fig. X.) As the valve forms no part of this invention, I do not limit myself to any particular construction, there being several constructions other thantheone illustrated which would answer the same purpose. y

The valve-stems are marked 2) b, and their upper ends are adapted for attachment to the wire ropes .c 0, These ropes extend over sheaves e e and to the station A, where they are connected to the rods f f. The rods f f are supported by means of brackets G G from the walls of the station, and they are weighted at their ends, the weights being denoted by D D. The object of attaching these weights to the threaded stems is to relieve the upward strain on the threads of the stem caused by the weight of the valve, thus reducing friction. The said rods are. also threaded, and the nuts through which the threaded parts of the rods move are represented by g g, and they are confined in the lower portions of the brackets, and revolved to raise and lower the said rods by means of hand-wheels E. It will be seen that by raising and lowering the rods f f the valves to a are opened and closed. Pointers h, which project from the rods f f, in connection with the graduated plates F F, fastened to the brackets O O, serve to indicate the positions of the valves, as will be readily understood.

As under some circumstances it becomes necessary to detach the valve-stems b b, inorder that the valves may be opened and closed independently of their connections,or. directly by hand, I use ordinary threaded valve-stems and nuts, and apply to the said nuts removable locks 2', which, when removed, allow the nuts to be elevated with the stems. When the locks are in place, all vertical motionof the stems independently of the nuts is prevented. WVhen the ropes are detached from the valve-stems, the locks iare'placed in position, and the opening and closing of the valves is accomplished by means of hand-wheels k.

I do not claim, broadly, the operation of a valve from a distance by means of a rope or chain which unites the hand-actuated device and the valvestem, as I am aware that such combination of devices is old; but I am not aware that a valve has been actuated from a distance by means of a rope attached to' the valve-stem and a screw-sten1 confined in a bracket carrying a hand-wheel and weighted to counterbalance the said valve.

I therefore claim as my invention- A regulating-station containing a series of screw-threaded stems mounted in brackets, each stem carrying a hand-wheel and being weighted as described, combined with a series of valves situated at points outside the sta tion, and ropes connecting the threaded stems in the station with the stems of the valves, whereby any valve in the series can be opened or closed by operating the threaded stem in the station connected therewith, substantially as set forth.

FRANCIS H. HAMBLETON.
